PRIORITY CLAIM

This application claims priority from U.S. Provisional Patent Application No. 62/187,078 filed on Jun. 30, 2015, which is incorporated by reference in the present application.

TECHNICAL FIELD

The disclosed embodiments generally relate to automatic generations of user path information based on detected user locations over time. More specifically, the disclosed embodiments relate to the use of Bluetooth Low Energy (BLE) tags or beacons to automatically generate user density and velocity maps for providing location-based services.

BACKGROUND

Automatic generation of user path information may benefit users and providers of location-based services. But current approaches to generating path information may not be able to provide real-time tracking of individual users. Instead, an environment may be provisioned with a static number of service locations and consistent staffing levels, regardless of user numbers or demands. In some situations, the number of service locations and the staffing level may be modified manually. For example, a teller may observe that checkout queues are long and customers are becoming dissatisfied, and broadcast a request for assistance. But such manual modification is imperfect, reactive, and based on limited knowledge about how users typically move, and are currently moving, through the environment. Automatic approaches may require expensive equipment, or lengthy installation and monitoring. These automatic approaches may be limited to simulations or trials, and may not be configured to provide information or services to users.

Currently, users may not be aware of underutilized queue or service locations, and may consequently select the slowest queue, or select a service location having long queues. This may delay the time to service and negatively affect the user's experience. Users traversing an environment may not be aware of the fastest path within the environment. For example, users may not be aware of the nearest exit in a facility, such as a movie theater or museum. Generally inconvenient, this lack of information may be dangerous in an emergency.

Consequently, there exists a need for systems and methods for automatic generation of user path information. These systems and methods may enable the provision of location-based services to users and to services providers.

SUMMARY

The disclosed embodiments may enable an automatic provision of location-based services to users and service providers. Service providers may use real-time path information to optimize the layout of an environment, or to modify the status of a queue or service location. For example, service providers may use real-time path information to identify underutilized or congested spaces in an environment, such as bottlenecks where user paths converge, or where user velocities decrease. As an additional example, service providers may modify an environment based on automatically gathered, real-time information about user paths. Service providers may modify queues disposed in an environment in response to real time path information. This modification may be based on current conditions and/or predicted future conditions. For example, the disclosed systems and methods may be configured to determine optimal staffing levels for service locations, potentially reducing the amount of time that users wait in queues. Automatic determination and modification of negative service location or queuing conditions may reduce time-lag, preventing overcompensation and wide swings in staffing levels and queue times. Automatic, real-time path information may also enable load sharing across multiple facilities or service locations by a service provider. For example, a service provider may be configured to indicate to a user a range of locations, together with expected service times. These indications may include paths from a start location to the service locations. The start location may be the current location of the user. By providing these indications the service provider may encourage users to visit underutilized service locations.

The disclosed embodiments may also provide location-based services to users. For example, automatically or in response to a user request, the disclosed embodiments may provide to a user a path to a desired product or service location. In emergency situations, the disclosed embodiments may route users, automatically or in response to a user request, to destinations, such as exits, along paths avoiding dangerous crowding or delays. The disclosed embodiments may also provide information about the expected time to reach a destination or perfect a service, such as the expected time in a queue before reaching a point-of-sale and/or completing a transaction at the point-of-sale.

The path maps may comprise data and/or instructions stored in a non-transitory memory. In certain aspects, the one or more path maps may be based on paths associated with user devices. For example, in some embodiments, path management unit 205 may be configured to determine paths based on sequences of user locations determined for user devices, such as user device 201. In certain aspects, path management unit 205 may be configured to determine user locations for user devices based on user data 11 received from user devices. For example, path management unit 205 may be configured to determine user locations for user devices, such as user device 201, based on distance information received from the user devices. In some embodiments, path determination may require interpolation of user device trajectories between points. For example, beacons may be configured to broadcast sensor identifiers once a second. A rapidly walking user may transport a user device six or more feet between identifier broadcasts. Similarly, a vehicle may transport a user device tens of feet in a second, for example a car on a highway traveling 100 miles per hour may transport a user device 100 feet in a second. Therefore, path management unit 205 may be configured to interpolate between identified locations to generate a path. A collection of paths for users may determine a path map.

In various aspects, paths may be anonymized. In some aspects, paths may be associated with sales data. For example, paths may be associated with items. For example, path management device 205 may be configured to associate paths with indications of items viewed or purchased by the user associated with the tracked user device. In some embodiments, path management unit 205 may be configured to generate and provide path maps using paths associated with one or more of products, product categories, financial transaction categories (e.g., method of payment, amount of purchase, returns), and users with selected demographic characteristics.

Consistent with disclosed embodiments, network 207 may enable the components of path management system 200 to communicate. In some embodiments, network 207 may include any combination of communications networks. For example, network 207 may include the Internet and/or any type of wide area network, an intranet, a metropolitan area network, a local area network (LAN), a wireless network, a cellular communications network, a Bluetooth network, a radio network, a near field network, or any other type of electronics communications network know to one of skill in the art. For example, beacons/receivers 203 may be configured to signal user device 201 over a Bluetooth network. As an additional example, user device 201 may be configured to provide user data 111 over a cellular network, at least in part, to path management unit 205.

Consistent with disclosed embodiments, environment 209 may be configured to communicate with one or more components of path management system 200. In some embodiments, environment 209 may comprise a retail or wholesale environment, a transportation environment, a public sector environment, or some other environment suitable for tracking user locations to generate aggregate user path information. For example, environment 209 may comprise a store, mall, shopping center, or warehouse. As an additional example, environment 209 may comprise a train station, bus depot, or an airport. As a further example, environment 209 may comprise a hospital or a prison. In some embodiments, environment 209 may comprise fixtures, as disclosed above. In certain embodiments, beacons/receivers 203 may be disposed all or partially within environment 209. In some embodiments, environment 209 may be configured to receive instructions 113 from path management system 205. For example, as disclosed above, environment 209 may be configured to receive instructions to change a status of a service location, modify an arrangement of fixtures, or modify a layout of products in environment 209. As would be recognized by one of skill in the art, numerous methods of receiving and implementing instructions 113 may be contemplated, and the envisioned embodiments are not intended to be limited to a particular method.

As would be recognized by one or ordinary skill in the art, the components and arrangement of the components included in path management system 200 may vary. Thus path management system 200 may comprise additional or alternative components to perform processes consistent with the disclosed embodiments. Furthermore, path management system 200 may include any number of user devices 201, beacons/receivers 203, path management units 205, networks 207, and environments 209, consistent with the disclosed systems and methods. In addition, operations attributed to particular components of system 200 may be distributed amongst other components of system 200, consistent with disclosed embodiments.

FIG. 3A depicts exemplary user device paths consistent with disclosed embodiments. The depicted first user device path (filled circles), and the second user device path (open circles), are disposed within an exemplary environment 209. This non-limiting exemplary environment 209 comprises a retail store. But one of skill in the art would recognize the applicability of the systems and methods disclosed herein to other environments. In certain aspects, environment 209 comprises fixtures, as described above. These fixtures may define aisles through which users (not shown) may transport the first and second user devices. In certain aspects, environment 209 may comprise components, such as one or more of entrance 301, first exit 303, first queue 304, second queue 305, point of service 306, and second exit 307. As would be recognized by one of skill in the art, the components of environment 209 are disclosed herein to illustrate the capabilities of the envisioned embodiments. The envisioned embodiments are not intended to be limited to environments comprises such components.

Consistent with disclosed embodiments, as depicted in FIG. 3A, environment 209 may comprise service locations (e.g., service location 306). Service location 306 may comprise a point of sale, such as a register, one or more queues, such as first queue 304 and second queue 305, an access point, such as entrance 301, first exit 303, and second exit 307, a facility, such as a department within a store, a store or restaurant within a mall, a musical performance within a venue, a unit within a hospital, a bay within a factory, a security checkpoint within an in airport or depot, or other location at which a user may receive or provide a good or service. For example, service locations may include entrance 301, first exit 303, and second exit 307. These service locations may comprise access points for environment 209. As would be recognized by one of skill in the art, these access points may have any suitable configuration that enables users to enter and exit environment 209. Similarly, in certain aspects, environment 209 may comprise service locations first queue 304 and second queue 305. In some aspects, first queue 304 and second queue 305 may comprise collections of users waiting for one or more goods or services. In some embodiments, one or more of first queue 304 and second queue 305 may comprise users physically arranged in a specific line or sequence. In certain arrangements, one or more of first queue 304 and second queue 305 may comprise a virtual queue. For example, users may receive an indication of priority, such as a number, and may be served according to that indicated priority. Consistent with disclosed embodiments, an expected wait time may be associated with each of first queue 304 and second queue 305. In certain aspects, environment 209 may comprise points of sale, such as register 306. Register 306 may comprise a cash register, a card reader, or any other fixed or mobile device for conducting a financial transaction known to one of skill in the art.

As depicted in FIG. 3A, a first user device and a second user device (associated with a first user and a second user, respectively) are transported through environment 209. Consistent with disclosed embodiments, path management system 200 may be configured to acquire a time series of user device locations corresponding to each of first user device and second user device. As shown, path management system 200 may be configured to periodically detect the location of one or more of the first user device and second user device. For example, one or more of user device 201, path management unit 205, or environment 209 may be configured to periodically determine the location of first user device. In some aspects, this detection may occur periodically. In certain aspects, this detection may occur aperiodically. For example, path management system 200 may be configured to generate user data comprising tuples of user device locations and times. In the non-limiting example shown in FIG. 3A, first user device and second user device are transported into environment 209 through entrance 301, through environment 301 to one of first queue 304 and second queue 305 at register 306, and then out of environment 301 through first exit 303. In this non-limiting example, the first user device is slowly transported to right upon entering environment 209, and then to the second queue 305. In contrast, the second user device is quickly transported to the center of environment 209 and then to first queue 304.

The times series of user device locations depicted in FIG. 3A may correspond to two users: a first user that enters a store, turns right, and proceeds slowly along the perimeter of the store until reaching an exit without a register (second exit 307), and turns back into the center of the store in search of a register (register 306); and a second user that rushes into the center of a store to retrieve a specific item and then goes to a register to exit (register 306). Based on such behavior, path management system 201 may be configured to provide instructions 113 to environment 209 or one of the user devices.

FIG. 3B depicts determination of a user device location from received location data consistent with disclosed embodiments. This non-limiting example concerns three beacons (two shown) and two user devices. In this non-limiting example, the beacons are mounted on fixtures 340 for clarity. One of skill in the art would appreciate that the beacons could be mounted elsewhere. As a non-limiting example, the beacons could also be mounted on a ceiling or overhead suspension mechanism. Each beacon may be configured to periodically transmit signals, as described above, such as BLE signals. Each user device may be configured to receive these transmitted signals. In some embodiments, each device may be configured to estimate a distance between the device and each beacon based on the transmitted signals. For example, the received signals may vary in strength depending on a distance between a user device and a beacon. The user device may be configured to estimate a distance between the user device and the beacon based on this signal strength. In certain embodiments, the user device may be configured to indicate discrete categories of signal strength. For example, a user device (e.g., user device 343) may be configured to indicate a first category of signal strength when the user device is within a near range (e.g., near range 313) of a beacon (e.g., first beacon 311). Similarly, a user device (e.g., user device 341) may be configured to indicate a second category of signal strength when the user device is within an intermediate range (e.g., intermediate range 315) of a beacon (e.g., first beacon 311). Furthermore, a user device (e.g., user device 343) may be configured to indicate a third category of signal strength when the user device is within a far range (e.g., far range 337) of a beacon. Each user device may simultaneously be receiving signals from multiple beacons. For example, user device 341 is within far range 337 of one beacon (not shown), intermediate range 315 of second beacon 321, and intermediate range 315 of first beacon 311. As an additional example, user device 343 is within far range 337 of one beacon (not shown), intermediate range 315 of second beacon 321, and near range 313 of first beacon 311. In some embodiments, the far range may be 30 to 100 or more feet, intermediate may be 3 to 30 feet, and near may be less than 3 feet. Alternatively or additionally, a user device may estimate a received signal strength indication, as would be understood by one of skill in the art.

Consistent with disclosed embodiments, in this non-limiting example, path management unit 205 may be configured to calculate distances between user device 201 and the first beacon 311, second beacon 313, and third beacon (not shown). In some embodiments, path management unit 205 may be configured to calculate distances based on a signal indicator associated with the beacon (as described above) and one or more of the range category and received signal strength indication. In certain embodiments path management unit 205 may be configured to receive signal indicators and one or more of the range category and received signal strength indication from user device 201. Alternatively or additionally, in some embodiments, path management unit 205 may be configured to receive distances calculated by first user device 201 based on one or more of the range category and received signal strength indication. While this non-limiting example has depicted the user device as a receiver interacting with beacons, one or ordinary skill in the art would recognize that user device may also act as a broadcaster. In such embodiments, receivers would replace the beacons depicted in FIG. 3A. Each receiver would determine one or more of a range category and received signal strength indication for the signals broadcast by the first user device and second user device. This range category and received signal strength indication would be provided to path management unit 205. For example, the receivers may be configured to provide this information to path management unit 205 over network 207. Path management unit 205 would be configured to determine locations for the first user device and second user device.

FIG. 4A depicts an exemplary user density map showing density regions consistent with disclosed embodiments. In some embodiments, path management unit 205 may be configured to calculate user density maps for environment 209. The user density maps may comprise data and/or instructions stored in a non-transitory memory. In some aspects, user density maps may indicate a spatial user density for environment 209. As described in greater detail below, path management system 200 may be configured to generate density maps to inform proper configuration of environment 209. For example, environment 209 may not be properly configured to encourage users to traverse all of environment 209. At the same time, environment 209 may be configured to channel users into high density regions, reducing user satisfaction.

Path management unit 205 may be configured to create a discretized representation of environment 209, consistent with disclosed embodiments. In some aspects, the discretized representation may comprise discrete elements, each discrete element having a density count. This density count may comprise a count of user paths traversing the discrete element. For example, path management unit 205 may be configured to partition a representation of environment 209 into a grid of discrete elements. In some aspects, path management unit 205 may be configured to assign a density value to each element in the grid based on the density count. The density value may be an unscaled value or a scaled value. The density value may be a normalized value, for example the density count normalized by the maximum, minimum, range, average, or median density count for the elements of the grid. In some embodiments, path management unit 205 may be configured to determine a change in densities between a first path map and a second path map.

As depicted in exemplary FIG. 4A, a user density maps may indicate regions of high user density, for example high density region 401A and 401B. High density regions may be defined with respect to historical densities or current user locations. Historical densities may include maximum densities over a time interval, average densities over a time interval, or some other measure of typical density known to one of skill in the art. High density regions may be defined statistically or with respect to a predetermined threshold. A definition of high density regions may be particular to environment 209, or independent of any particular environment. For example, high density regions may be defined with respect to a percentile, such at a 75%, 80% or 90% percentile of user densities for a user density map of environment 209. As an additional example, high density regions may be defined with respect to an average user density and a standard deviation of user densities, such as a user density more than one standard deviation greater than the average user density. As a further non-limiting example, a region of high time-averaged density may comprise discrete elements having greater than 0.5 paths per square meter, and/or a region of high instantaneous density value may comprise discrete elements having greater than 1.5 paths per square meter. Particular threshold values may depend on environment 209 and the examples provided are not intended to be limiting. As shown in FIG. 4A, high density regions may be associated with user behaviors, such as, in non-limiting examples, turning right upon entering a store (e.g., high density region 401A), or a junction of common user pathways (e.g., high density region 401B).

As further depicted in exemplary FIG. 4A, user density maps may indicate regions of low user density, for example low density region 403A and 403B. Low density regions may be defined with respect to historical densities or current user locations. Historical densities may include maximum densities over a time interval, average densities over a time interval, or some other measure of typical density known to one of skill in the art. Low density regions may be defined statistically or with respect to a predetermined threshold. A definition of low density regions may be particular to environment 209, or independent of any particular environment. For example, low density regions may be defined with respect to a percentile, such as the 25%, 20% or 10% percentile of user densities for a user density map of environment 209. As an additional example, low density regions may be defined with respect to an average user density and a standard deviation of user densities, such as a user density less than one standard deviation less than the average user density. As a further non-limiting example, a region of low user density may comprise discrete elements having time-averaged density less than 0.05 paths per square meter (i.e., a region traversed by a single user per square meter every 20 units of time), and/or a region of low density may comprise discrete elements having instantaneous density values less than 0.1 paths per square meter (i.e., a region of 10 square meters containing a single user). Particular threshold values may depend on environment 209 and the examples provided are not intended to be limiting. As shown in FIG. 4A, low density regions may be associated with user behaviors, such as, in non-limiting examples, avoidance of out-of-the way corners of a store (e.g., low density region 403A), or avoidance of apparent dead-ends (e.g., low density region 403B). This avoidance may negatively impact item sales, such as sales of item 405.

User density maps may be associated with metadata, consistent with disclosed embodiments. In some embodiments, path management unit 205 may be configured to generate and provide user density maps based on path maps for certain selections of one or more of products, product categories, financial transaction categories (e.g., method of payment, amount of purchase, returns), and users with selected demographic characteristics. As a non-limiting example, a user density map may indicate the density of users in environment 209 that purchased more than $100 worth of products, or the density of 18-to-34-year-old users in environment 209. In some embodiments, path management unit 205 may be configured to provide user density maps as heatmaps for display on an electronic display associated with one or more of user device 201, path management unit 205, and environment 209.

FIG. 4B depicts an exemplary user velocity map showing velocity regions consistent with disclosed embodiments. In some embodiments, path management unit 205 may be configured to calculate user velocity maps for environment 209. The user velocity maps may comprise data and/or instructions stored in a non-transitory memory. In some aspects, user velocity maps may indicate a user velocity field for environment 209. As described in greater detail below, path management system 200 may be configured to generate velocity maps to inform proper configuration of environment 209. For example, environment 209 may be improperly configured to encourage users to traverse portions of environment 209 at excessive speeds. At the same time, environment 209 may be improperly configured to channel users into regions of low velocity, reducing user satisfaction.

As described above, path management unit 205 may be configured to create a discretized representation of environment 209, consistent with disclosed embodiments. In some aspects, the discretized representation may comprise discrete elements, each discrete element having an average velocity. This average velocity may depend on the velocities of user paths traversing the discrete element. For example, a velocity may be defined for each path traversing the discrete element. In some aspects, the average velocity may comprise the vector sum these velocities divided by the number of paths. In certain aspects, the average velocity may comprise the normalized vector sum of these normalized versions of these velocities (i.e., the average direction). In some aspects, path management unit 205 may be configured to assign a velocity value to each element in the grid based on the average velocity. The velocity value may be an unscaled value or a scaled value. The velocity value may be a normalized value, for example the average velocity normalized by the maximum, minimum, range, average, or median of the magnitudes of the average velocities for the elements of the grid. In some embodiments, path management unit 205 may be configured to determine a change in average velocity between a first path map and a second path map.

As depicted in exemplary FIG. 4B, user velocity maps may indicate regions of high user velocity, for example high velocity region 409. High velocity regions may be defined with respect to historical velocities or current user velocities. Historical velocities may include maximum velocities over a time interval, average velocities over a time interval, or some other measure of typical velocities known to one of skill in the art. High velocity regions may be defined statistically or with respect to a predetermined threshold. A definition of high velocity regions may be particular to environment 209, or independent of any particular environment. For example, high velocity regions may be defined with respect to a percentile, such as the 75%, 80% or 90% percentile of user velocities for a user velocity map of environment 209. As an additional example, high velocity regions may be defined with respect to an average user velocity and a standard deviation of user velocities, such as a user velocity more than one standard deviation greater than the average user velocity. As a further non-limiting example, a high velocity region may comprise discrete elements with average velocity values greater than 1 meter per second, when environment 209 is, as a non-limiting example, a store. As a further non-limiting example, a high velocity region may comprise discrete elements with user velocities greater than 20 meter per second, when environment 209 is, as a non-limiting example, a road. Particular threshold values may depend on environment 209 and the examples provided are not intended to be limiting. As shown in FIG. 4A, high velocity regions may be associated with user behaviors, such as, in non-limiting examples, first entering a store (e.g., high velocity region 409).

As depicted in exemplary FIG. 4B, user velocity maps may indicate regions of low user velocity, for example low velocity region 407. Low velocity regions may be defined with respect to historical velocities or current user velocities. Historical velocities may include maximum velocities over a time interval, average velocities over a time interval, or some other measure of typical velocities known to one of skill in the art. Low velocity regions may be defined statistically or with respect to a predetermined threshold. A definition of low velocity regions may be particular to environment 209, or independent of any particular environment. For example, low velocity regions may be defined with respect to a percentile, such as the 25%, 20% or 10% percentile of user velocities for a user velocity map of environment 209. As an additional example, low velocity regions may be defined with respect to an average user velocity and a standard deviation of user velocities, such as a user velocity less than one standard deviation less than the average user velocity. As a further non-limiting example, a low velocity region may comprise discrete elements with average velocity values less than 0.1 meter per second, when environment 209 is, as a non-limiting example, a store. As a further non-limiting example, a low velocity region may comprise discrete elements with user velocities less than 2 meter per second, when environment 209 is, as a non-limiting example, a road. Particular threshold values may depend on environment 209 and the examples provided are not intended to be limiting. As shown in FIG. 4A, low velocity regions may be associated with user behaviors, such as, in non-limiting examples, user queuing in front of a service location (e.g., low velocity region 407).

User velocity maps may be associated with metadata, consistent with disclosed embodiments. In some embodiments, path management unit 205 may be configured to generate and provide user velocity maps based on path maps for certain selections of one or more of products, product categories, financial transaction categories (e.g., method of payment, amount of purchase, returns), and users with selected demographic characteristics. As a non-limiting example, a user velocity map may indicate the velocities of users in environment 209 that purchased more than $100 worth of products, or the velocities of 18-to-34-year-old users in environment 209. In some embodiments, path management unit 205 may be configured to provide user density maps as heatmaps for display on an electronic display associated with one or more of user device 201, path management unit 205, and environment 209.

FIG. 5 depicts an exemplary schematic showing exemplary instructions 113 provided by path management system 200, consistent with disclosed embodiments. In some embodiments, path management unit 205 may be configured to receive a request for information from user device 201. In certain aspects, the request may concern one or more of a product type, route, and a service location. For example, path management unit 205 may be configured to receive a request for a service location matching certain criteria (e.g., service location type, wait time, distance from user, or similar characteristics of a service location). Path management unit 205 may be configured to determine, based on one or more of a path map, user density map, and user velocity map, a selection of service locations meeting the selection criteria. For example, path management unit 205 may be configured to determine an expected wait time at a service location based on one or more of user velocities at the service location, individual paths recorded in a path map traversing the service location, and determined correlations between historical measures of user velocity and/or user density and historical wait times. As an additional example, path management unit 205 may be configured to receive a request for a product or product type matching certain criteria. As described above with respect to FIG. 2, path management unit 205 may be configured with product and inventory information for environment 209. Path management unit 205 may be configured to determine one or more products matching the specified criteria.

Consistent with disclosed embodiments, path management unit 205 may be configured to provide instructions 113 responsive to the above-discussed request. In certain aspects, path management unit 205 may be configured to provide instructions 113 to user device 201. For example, when the request concerns a product, or product category, instructions 113 may comprise one or more products satisfying the request criteria. As an additional example, when the request concerns a service location, instructions 113 may comprise one or service locations satisfying the request criteria. In some embodiments, path management unit 205 may be configured to provide a route. In certain aspects, the route may be provided in response to a request for a route. For example, path management unit 205 may be configured to receive a request from user device 201 for a route from a first location. In some aspects, the first location may correspond to a location of the user device 201. In certain aspects, the first location may be specified in the request. In various aspects, the second location may be specified in the request. In some aspects, the second location may correspond to one or more of a product or service location, for example, a product or service location specified in the

For example, path management unit 205 may be configured to receive a request from user device 201 for a route from a first location to a second location in environment 209. As an additional example, environment 209 may comprise a road network, and the first location and second location may comprise geographic locations reachable using the road network. As a further example, environment 209 may comprise a store, the first location may comprise a location of user device 201, and the second location may comprise one or more of a product location or a service location. In some embodiments, path management unit 205 may be configured to receive the request for a route in response after providing instructions 113 concerning a requested product, product category, or service location.

Path management unit 205 may be configured to determine a route in response to a received request. In some embodiments, path management unit 205 may be configured to determine the route based on one or more of the path map, density map, and velocity map. For example, as shown in FIG. 5, path management unit 205 may be configured to determine a route from user device location 505 to one or more of item 405, service location 501, third queue 503, or second exit 307. This route may be configured to avoid low velocity region 407. Similarly, path management unit 205 may configure a route to avoid a high density region. In some aspects, path management unit 205 may be configured to determine routes based on paths corresponding to user devices. For example, path management unit 205 may be configured to determine routes based on elapsed times for paths between the paths traversing the beginning and end of the route.

FIG. 6 depicts an exemplary schematic showing exemplary modifications to environment 209 according to instructions 113 provided by path management system 200, consistent with disclosed embodiments. In some embodiments, path management unit 205 may be configured to determine instructions 113 automatically. In certain embodiments, the instructions 113 may comprise instructions to change a status of one or more of a point of service, queue, and staffing level of at least part of a service location. For example, path management unit 205 may be configured to determine when the expected wait time at a service location or queue rises above (or falls below) a predetermined threshold. In some aspects, path management unit 205 may be configured to provide instructions to open additional (or close existing) service locations or queues based on this determination. Similarly, path management unit 205 may be configured to determine whether to increase or decrease the number of personnel at a service location, based on a customer density at the service location. For example, path management system 205 may be configured to detect that a queue at a point of sale exceeds a predetermined wait time and provide instructions to open another register at the point of sale. In some embodiments, path management system 205 may be configured to provide instructions to one or more of the users in the queue, for example through a user device, to move to another point of sale. Path management system 205 may be configured to provide a path to this secondary point of sale. As another example, path management system may be configured to determine, based on one or more of the path map, velocity map, and density map, that customers of a store are wandering the menswear department and provide instructions for dispatching sales associates from another department to assist them.

In some embodiments, path management unit 205 may be configured to provide one or more of instructions to modify a product layout and instructions to modify a fixture arrangement. In some embodiments, path management system 205 may be configured to determine a modified arrangement of fixtures. In certain embodiments, path management system 205 may be configured to provide one or more of a path map, density map, and velocity map to another entity, computer, or program that determine a modified arrangement of fixtures. In some aspects, path management system 205 may be configured to receive instructions 113 from such an entity, computer, or program and convey the instructions 113 to environment 209. The modified arrangement of fixtures may be derived to increase sales or profitability, improve employee or customer satisfaction, improve a safety metric (such as an evacuation time or response time), or other similar metrics known to one of skill in the art. As shown in exemplary FIG. 6, environment 209 may be modified in accordance with instructions 113. For example, environment 209 may be modified to include modified fixtures 601, 603, and 605A-605D. In some embodiments, path management unit 205 may be configured to determine a second path map based on user data 111 received after implementation of instructions 113. For example, as shown in FIG. 6, path management unit 205 may be configured to determine, based on received user data 111, that modified fixtures 605A-605D eliminated high velocity region 409, increasing sales for nearby items; and that low density regions 403A and 403B have been eliminated. But as shown by the second density map, new high density region 607 remains. Based on the determined high density region 607, path management system 205 may be configured to provide additional instructions 113. Thus path management system 200 may enable the iterative, real-time modification of environment 209 to optimize metrics as described above.

FIG. 7 depicts a flowchart illustrating exemplary operations of a method for path management. In step 501, path management system 200 may be configured to detect a user, consistent with disclosed embodiments. In some embodiments, user device 201 may be configured to broadcast information. For example, user 201A may configure user device 201 to broadcast information using an application running on user device 201. As an additional example, user device 201 may be configured to broadcast information automatically. For example, upon entering environment 209, a BLE enabled application, or a BLE tag may be configured to sense a BLE beacon. In some embodiments, the BLE enabled application, or BLE tag may be configured to alert path management system 200 of the presence of the user device 201. In certain embodiments, the user device may be configured to execute a software application facilitating detection of user device 201 by beacons/receivers 203. In some aspects, such an alert may also alert path management system 200 to the presence of user 201A.

Path management system 200 may be configured to detect a user in step 503, consistent with disclosed embodiments. As described above with respect to FIGS. 2, 3A and 3B, path management system 200 may be configured to periodically receive indications of distance from one or more of user device 201 and beacons/receivers 203. For example, user device 201 may be configured to provide one or more of distance categories, received signal strength indications, estimated distances, and determined user device locations to path management unit 205 based on broadcast beacon signal identifiers. As an additional example, beacons/receivers 203 may be configured to provide one or more of distance categories, received signal strength indications, and estimated distances from user device 201 based on broadcast user device signals. For example, user device 201 may be configured to broadcast signal identifiers. In certain aspects, based on one or more of distance categories, received signal strength indications, and estimated distances, path management unit 205 may be configured to determine locations for user device 205. In various aspects, based on determined and/or received user device locations, path management unit 205 may be configured to determine user paths.

Path management system 200 may be configured to perform real time path analysis in step 505, consistent with disclosed embodiments. As described above, with respect to FIG. 2, path management unit 205 may be configured to determine path maps for environment 209. As further described above, with respect to FIGS. 4A and 4B, in some embodiments, path management unit 205 may be configured to generate a user density map and/or a user velocity map.
